The klystron was invented at Stanford University in 1937 and originally used as the oscillator in radar receivers during World War II. A klystron tube makes use of speed-controlled streams of electrons that pass through a resonating cavity. Electrons in a klystron are accelerated to a controlled speed by the application of several hundred volts.

Weather radars send directional pulses of microwave radiation, on the order of a microsecond long, using a cavity magnetron or klystron tube connected by a

The klystrons at the ALS "broadcast" down special tubes and cables, called waveguides, that lead to the linac, booster synchrotron, and storage ring. The NWS Radar site displays the radar on a map along with forecast and alerts. The radar products are also available as OGC compliant services to use in your application.

Een klystron is een elektronenbuis van het type inhaalbuis met twee of meer inwendige trilholten om microgolven met hoge vermogens te versterken of te genereren. De versterkingsfactor van klystrons kan hoog zijn, 60 dB (een miljoen) of meer, met uitgangsvermogen tot enkele tientallen megawatt, maar de bandbreedte is smal, meestal een paar procent, hoewel het in sommige apparaten tot 10% kan zijn.

This system is designed for operation in environments where access to a conventional S-band frequency is not available. 2021-02-20 2021-02-11 Bay News 9 is a cable news television network located in St. Petersburg, Florida.

A klystron uses the kinetic energy of an electron beam for the amplification of a high-frequency signal. Klystrons make use of the transit-time effect by varying the velocity of an electron beam. It is a linear beam device; that is, the electron flow is in a straight line focused by an axial magnetic field. A klystron serves as the source of high-power microwaves in this weather radar system. Source: Selecs (Click image to enlarge) At one end of the tube, a uniform beam of electrons is generated at a cathode and accelerated by an anode to travel through the tube toward a collector at the other end. 2020-08-19 Check Spectrum News 13's StormTracker 13 Interactive Radar to get detailed, street-level conditions for Orlando and Central Florida.
